Oxygen and hydrogen are at the same temperature T. What is the ratio of kinetic energies of oxygen molecule and hydrogen molecule when oxygen is 16 times heavier than hydrogen ?

Explanation

To solve the problem of finding the ratio of kinetic energies of oxygen and hydrogen molecules at the same temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Kinetic Energy Formula**:
The kinetic energy (KE) of a gas molecule is given by the formula:
\[
KE = \frac{3}{2} k_B T
